As the EMD 567s got worn, Many Railroads underwent rebuild programs to prolong the life of their locomotives. One Program in particular was the Uceta GP-16 program on the SCL. Starting in 1979 they took many of their GP7s, GP9s, and GP18s and replaced the existing 567 prime movers with 16cyl 645C Power Assemblies. This combination resulted in a unique sound never before released in the Model Railroad Market.
There were a number of these rebuild programs by many railroads. CN Had GP9RMs, The DM&IR had SD-Ms rebuilt from SD9's and SD18's and others. While there were different Exhuast configurations, This file will be very close to the following locomotives:
GP16, FP9U, GP9RM, SD9M, SD-M, GP7U (Some- Check your prototype)
The following locos were rebuilt from 567D Turbo locos, that have been de-turboed and repowered with the 645C Power Assemblies:
GP20E, GP20M, GP35M, GP35R, GP38M, SD18M, SD20-2, SD35R, SD20
Recorded from a EMD SD-M
This project is a normal idle version. It has 2 exhaust stacks.
File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual notching. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.
Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.

Auto Bell:
Many Second and Third Generation locomotives have been fitted with an Automatic Bell that is triggered when the horn is blown. In MANY cases this cannot even be bypassed on modern locos. Before the FRA mandated this feature on new locomotives the bell was of course turned on and off separately. Some locomotives were delivered with a manual bell and have been converted to an automatic bell. This creates a challenge in sound file creation.
We realize that not every loco with a particular prime mover had this feature. As such we have built in an option to turn the feature on and off. We will set the default in the file to be what is most appropriate for the particular file.
To turn the feature OFF - Auto Bell OFF:
1. Remove the Auto bell sound slot from the function mapping chart

The Pioneer Zephyr is a diesel-powered trainset built by the Budd Company in 1934 for the Chicago, Burlington & Quincy Railroad (CB&Q), commonly known as the Burlington Route. The trainset was the second internal-combustion–powered streamliner built for mainline service in the United States (after the Union Pacific Railroad's M-10000), the first such train powered by a diesel engine, and the first to enter revenue service.
The trainset consists of one power/storage car, one baggage/RPO/buffet/coach car, and one coach/observation car. The cars are made of stainless steel, permanently articulated together with Jacobs bogies. The construction incorporated recent advances such as shotwelding (a specialized type of spot welding) to join the stainless steel, and unibody construction and articulation to reduce weight. It was the first of nine similarly built trainsets made for Burlington and its technologies were pivotal in the subsequent dieselization of passenger rail service.
Its operating economy, speed, and public appeal demonstrated the potential for diesel-electric-powered trains to revitalize and restore profitability to passenger rail service that had suffered a catastrophic loss of business with the Great Depression. Originally named the Burlington Zephyr during its demonstration period, it became the Pioneer Zephyr as Burlington expanded its fleet of Zephyr trainsets.
On May 26, 1934, it set a speed record for travel between Denver and Chicago when it made a 1,015.4-mile (1,633 km) non-stop "Dawn-to-Dusk" dash in 13 hours 5 minutes at an average speed of almost 78 mph (124 km/h). For one section of the run, it reached a speed of 112.5 mph (181 km/h). The historic dash inspired a film ("The Silver Streak") and the train's nickname, "The Silver Streak".
The train entered regular revenue service on November 11, between Kansas City, Missouri; Omaha, Nebraska; and Lincoln, Nebraska. It operated this and other routes until its retirement in 1960, when it was donated to Chicago's Museum of Science & Industry, where it remains on public display. The train is generally regarded as the first successful streamliner on American railroads.
Though no Pioneer Zephyr runs today, we used an 8-567C prime mover for this project.
This project is a normal idle version. It is an air throttle version. It has switcher type exhaust with a single exhaust stack.

The ALCO 251 prime mover was the most popular and abundant prime mover ever made by the company. While it proved to be quite successful, it sadly outlived its original manufacturer. ALCO closed their doors in 1969. The 251 prime mover is actually still available to purchase today from Fairbanks Morse for use in marine, generator and locomotive uses.
Our recording is from a 16cyl 251B and could be found in the following locomotives:

The GE FDL-16 prime mover was first used in 1959 in the General Electric U25B locomotive. Over the years little changed in terms of sound until the "Dash-8" series of GE locomotives was introduced. Known for their throaty chug and shaft driven compressor (rather than the more modern “Whoop” electric compressor). There was an interim period following the "U Boats" that began the era in GE called the "Dash-7s". During this time many locos started receiving exhaust silencers and the shape of the exhaust changed to the "Bathtub" type. This created a subtle change in sound. The following GE locomotives used the 16cyl FDL prime mover with this type of configuration.
Locomotives:
B30-7, B36-7, C30-7, C36-7, and others.
The following locomotives would use early 16cyl FDL configurations, but this file would work for them as it is very close. Check your prototype as some of the later “U boats” were upgraded with more modern exhausts. You could also use our 73445/74445 GE 16cyl FDL Early file:
U25B, U28B, U30B, U33B, U36B, U25C, U28C, U28CG, U30C, U30CG, P30CH, U34CH, U33C, U36C

Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual nothing. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.

Auto Bell:
Many Second and Third Generation locomotives have been fitted with an Automatic Bell that is triggered when the horn is blown. In MANY cases this cannot even be bypassed on modern locos. Before the FRA mandated this feature on new locomotives the bell was of course turned on and off separately. Some locomotives were delivered with a manual bell and have been converted to an automatic bell. This creates a challenge in sound file creation.
We realize that not every loco with a particular prime mover had this feature. As such we have built in an option to turn the feature on and off. We will set the default in the file to be what is most appropriate for the particular file.
To turn the feature OFF - Auto Bell OFF:
1. Remove the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8
----------------------

2. Change the sound configuration of the Auto bell sound slot

To turn the feature ON - Auto Bell ON:

The GE 44-ton switcher is a 4-axle diesel-electric locomotive built by General Electric between 1940 and 1956. The locomotives were available with a choice of prime movers. Most were built with a pair of Caterpillar Inc.'s D17000 V8 180 horsepower (134 kW) engines. It was designed for industrial and light switching duties, often replacing steam locomotives that had previously been assigned these chores. This locomotive's specific 44-short ton weight was directly related to one of the efficiencies the new diesel locomotives offered compared to their steam counterparts: reduced labour intensity. In the 1940s, the steam to diesel transition was in its infancy in North America, and railroad unions were trying to protect the locomotive fireman jobs that were redundant with diesel units. One measure taken to this end was a stipulation that locomotives weighing 90,000 pounds (41,000 kg) or more required a fireman in addition to an engineer. The 44-ton locomotive was born to skirt this requirement. Other manufacturers also built 44-ton switchers of center-cab configuration. 348 examples of this locomotive were built for North American railroads. Many remain, in service and in museums.

Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.

The ALCO 251 prime mover was the most popular and abundant prime mover ever made by the company. While it proved to be quite successful, it sadly outlived its original manufacturer. ALCO closed their doors in 1969. The 251 prime mover is actually still available to purchase today from Fairbanks Morse for use in marine, generator and locomotive uses.
Our recording is from a 16cyl 251C and could be found in the following locomotives:
C425, C628
Other locomotives using variations of the 16cyl 251 prime mover included:
RS27, C424, C430, RSD-15, C630, C636, WDM-2 (Indian Railways)

The 1500 horsepower 8cyl version of the 251F could be found in the following locomotives:
C-415
The C415 was a large switcher or small road switcher equipped with a raised cab mounted slightly off-center, with a lower, narrower hood on either side. The longer one contained the diesel engine, a 1,500 hp (1.1 MW) eight-cylinder turbocharged Alco 251-F, while the shorter contained auxiliaries. The C415 could be ordered with three different cab heights; a low one for minimum clearances, a regular height one, and an extra-height one for maximum visibility.
Trucks fitted were either Type B road trucks or ALCO Hi-Ad (high adhesion).

GE Evolution 12cyl "GEVO" Locomotives have a 4 stoke diesel engine and have been designed to be more efficient and more emission friendly than previous models. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference, though admittedly there is little sound difference if any between the two.
All early GEVOs were delivered with the Nathan Airchime K5HL air horn. Later GEVOs started to recieve a slightly different K5HLL horn. Most if not all have been delivered with a Graham-White 373 E-Bell. This E-Bell is tied to the horn circuit in the locomotive and will play automatically when the horn is played. The ESU version also has this new feature. The bell can be activated by either pressing F1 or by pressing the horn using F2. The "Auto-Bell" can be turned off by removing the the Auto-Bell sound slot from F2.
Another feature of the prototype is "Smart Start". For the sake of both emissions and fuel savings all GEVOs have been built with an auto shutdown/auto start feature. After the loco has been idle for a period time, the engine will shut down on its own. If the prime mover cools to a certain temperature the loco will automatically start again to keep from freezing.

Auto Bell:
Many Second and Third Generation locomotives have been fitted with an Automatic Bell that is triggered when the horn is blown. In MANY cases this cannot even be bypassed on modern locos. Before the FRA mandated this feature on new locomotives the bell was of course turned on and off separately. Some locomotives were delivered with a manual bell and have been converted to an automatic bell. This creates a challenge in sound file creation.
We realize that not every loco with a particular prime mover had this feature. As such we have built in an option to turn the feature on and off. We will set the default in the file to be what is most appropriate for the particular file.
To turn the feature OFF - Auto Bell OFF:
1. Remove the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8
----------------------
CV311 = 4
2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1
----------------------
CV287 = 0
To turn the feature ON - Auto Bell ON:
1. ADD the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8
----------------------
CV311 = 12
2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1
----------------------
CV287 = 1
Auto Bell Timer:
The Bell timer is amount of time the bell will play after the horn if the auto timer is active. The timer is broken down into 1/4 of a second increments.

CV169=8 - 2 Seconds
CV169=12 - 3 Seconds

GE 16-7FDL16Y9 LATE EXH Ed2 H0 N XL L M4
- Article numbers:S0813
- Last change: 1/7/2026
- Manufacturer: ESU
In the Mid 1980s GE changed it's 16cyl FDL design to include a different exhaust silencer, a new electric compressor often known as the "Whoop compressor" and changed some of the electronics of their locomotives. These differences among a few other led to a distinct change in the sounds from the GE 16cyl FDL often found from the U25Bs on through the Dash-7 series of the Locomotives.
GE's AC series of locomotives were introducted in 1994. They share the same carbody design and many of the internal components as the Dash-9 series, except they are equipped with AC traction motors instead of the conventional DC versions. The cab air conditioner was moved from the left (conductor's) side walkway to a position under the cab floor to make space for the six traction inverters (one per axle) that supply the AC current to the traction motors.
The "Modern" GE 7FDL 16Cyl Prime mover can be found in the following Locos:
Dash 8-39B, Dash 8 40-B, Dash 8-40BW, Dash 8-39C, Dash 8-40C, Dash 8-40CM, Dash 8-40CW, Dash 8-41CW, Dash 8-44CW, Dash 9-40C, Dash 9-40CW, Dash 9-44CW, C38EMi, C38AChe, AC4400CW
Some AC6000CW were built with 7FDL-16cyls and were later converted to 7HDL-16cyl. Some were never converted. Please refer to the prototype for reference.
Passenger Locos including: P40DC, and P42DC were built slightly different and contained HEP.
Recorded from a GE AC4400CW
This project has an automatic low & high idle. It has a single late (silenced) exhaust stack.
File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual notching. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.
Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.
